I agree with that as well. Exercise is great, but sometimes when someone is so depressed that they can't get out of bed, exercise is not an option for treatment. Or if because of their occupational stress injury they also face physical injuries, and they can't operate physically in the way they once did, exercise in itself can be a trigger for the loss of what they were able to do once and are no longer able to do. It's contextual.
